Hi Barry,
Sure thing...

Just clarifying because we have such diversity in language in the forum....

The term of offsetting the thread form.... if we use "moi's offset command" you would get erroneous results.... but the term offset, as in "move the cutting form in and out of the cut, is how a guy actually making a nut and bolt would do it...

I am pretty sure you got that part.... just adding it in for the forum....

Always like watching your work go by.....
